Abstract: A method and apparatus for fusing and shaping the end of a rope, cord or the like made of heat fusible fibers avoiding the enlarged or bulbous end which normally occurs when heated in a conventional manner. The method involves inserting the cut end of a rope into a cavity of a member wherein the cavity tapers inwardly in a direction from an open end thereof to a closed bottom end, heating the member to melt the end of the rope thereby fusing together the strands and cooling the heated end of the rope to set the fused ends and shape the same to the internal shape of the cavity. The apparatus is a thin-walled, metallic member conically shaped and located at the end of a handle. A flared sleeve is also provided in which the end of the rope to be fused is inserted to compress the strands together before being heated. The conical member maybe heated by a butane torch or the like or alternatively, an electric resistance heating element maybe incorporated in a stem projecting from the handle.

Abstract: A light weight and inexpensive sampling device to sample the respirable fraction of aerosols in a work environment on a continuous basis is described. The device consists of a short length of capillary tubing having an internal diameter of about 1.3 mm in a series with a somewhat longer length of capillary tubing having an internal diameter of about 0.5 mm which acts as a collector or sampler and which is in turn connected to an aspirating device. The sampler tube may be wound on a spool which is so small that the entire device is button sized and may be conveniently worn on the lapel as a personal monitoring device. The trapped respirable aerosol particles may be washed out of the sampler periodically for counting and/or chemical analysis.

Abstract: A process for fabricating tubes from a quaternary 3.5% Sn, 1% Mo, 1% Nb balance Zr alloy by hot extrusion, cold working and heat treatment so that the tubes have small grains that have low dislocation densities. The tubes are superior to the standard cold worked Zr-2.5 wt % Nb tubes because during service in CANDU-PHW reactors they (a) have lower axial elongation and diametral expansion and (b) the hydrides are less susceptible to reorientation from the circumferential-axial plane into the radial-axial plane.

Abstract: A device for measuring rib hump angle in the diagnosis of scoliosis, which comprises a frame, a plurality of stiff, laterally spaced parallel finger-like members arranged in pairs along one side of the frame with the two members of each pair equally spaced on opposite sides of the centerline of the edge, and frictionally slidable on the frame parallel to the centerline of the edge, so that when the frame edge is transverse and perpendicular to the longitudinal axis of the spine each finger-like member can be pushed into contact with the back. Means are also provided on the frame to measure the angle subtended between a first line perpendicular to the movement of the fingers and a second line intersecting the first line and passing through a selected point on the highest finger on the "high" side of the spine and the corresponding point on the other finger of the pair on the other or "low" side of the spine, so that rib hump angle can be measured directly.

Abstract: A process for treating cereal grains and particularly oats, to separate the endosperm from the remainder of the kernel without dry milling. The grains are soaked in an aqueous medium having a pH of 3.0-7.0 at a temperature in the range 40.degree.-70.degree. C. for sufficient time to absorb at least an equal weight of the liquid medium. The conditions are such that the endosperm portion of the grain liquefies, as opposed to softens. The grain may be crushed in a variety of ways to split the husk and release the liquid endosperm contents which are then dispersed in water. The endosperm solids can be recovered from dispersion, following a screening step to separate the husks by drying to yield a substantially white, lower fiber whole endosperm flour product. Alternatively, the dispersion may be sedimented and/or centrifuged to produce a wet solids fraction and a soluble fraction, each of which can be subsequently recovered in dry form.

Abstract: A relatively inexpensive electronic delay timer particularly suitable for portable use in such applications as control of a camera shutter. The timer can be used in either a leading or trailing mode and employs a small 6V battery as a power source. An integrated circuit timer device is arranged to provide an output signal at the end of a time delay period which can be variably selected by means of a built-in capacitive-resistive network and which is arranged to start in response to a movement of an external control switch. The output signal triggers a second time period of predetermined duration in a second integrated circuit timer during which time a second output signal is generated thereform which is used to activate a transistor device, allowing a capacitor in the circuit to discharge therethrough and through a solenoid which is mechanically coupled to the camera shutter. When the second output signal ceases, at the end of the second time period, the transistor is deactivated and the capacitor recharges.

Abstract: A simple and inexpensive device for measuring radial expansion of tube-like structures which is particularly useful to measure male potency. A radially expansible loop comprising a flexible, relatively slippery tube made from a material such as paper or a thermoplastic film having an elongated tail of the same or different material extending therefrom is drawn tight around the flaccid penis, by means of draw means at the end of the tail, and held in place by an adhesive patch. Should an erection occur the tail slides partially out of the tube to accommodate the radial expansion which occurs and remains in the extended position until manually retracted by pulling the draw means at the end of the tail. The radial expansion can be assessed by measuring the extension of the tail exposed.
